Plates 1-12 referenced in the thesis are also attached to this record.Palynological investigations of a peat deposit from a small sinkhole bog, Button bush Bog, and two archaeological sites, Round Spring Shelter, Round Spring Site 23SH19, and Gooseneck Site 23CT54 located in Shannon and Carter counties Missouri, provide a vegetational record for the last 3100 years in the southeast Ozarks. The Buttonbush Bog core has a basal radiocarbon date of 3130 ± 100 years B.P. Pollen spectra from the basal zone indicate a mixed oak forest with minor components of pine and hickory. Shortly thereafter, pine becomes more abundant, suggesting the presence of a pine-oak forest that has undergone very little change to the present. A small Ambrosia rise indicates land clearance and pioneer settlement about 165 years ago. The pollen sequence from Round Spring Shelter also suggests the presence of a pine-oak forest in the vicinity of Round Spring. However, the pollen spectra from Gooseneck Site 23CT54 indicate a mixed oak-hickory forest in the locality during the time of Indian occupation. Preliminary analysis of the fossil phytoliths from Gooseneck indicates that four grass subfamilies may have grown at the site.en-USUniversity of Minnesota DuluthPlan As (thesis-based master's degrees)Department of Earth and Environmental SciencesMaster of ScienceMaster of Science in GeologyThesis or Dissertation
